OK, without giving it much thought (meaning you'll have to do the
program yourself). You could add something like this to your .profile:
du () {
# Check for options, make sure they're correct
case $option
f)
OPTS=" ${OPTS} -abc"
;;
*)
;;
esac
/usr/bin/du $(OPTS)
}

Almost all are just links/references ;-)
But yes, i actually found the currently valid site, it's 'www.ibb.net'.
(i seem to have had the wrong search engine before)
And now i know why it was so hard to find it:
Event the current page stronlgy recommends to bookmark 'www.ibbnet.org',
which is an invalid address(!) It must have been valid earlier
and has no DNS anymore...

But you haven't mentioned if you tried "stty erase <ctrl-v><backspace>".

I just found "Consistent BackSpace and Delete Configuration" again.

This actually has some use beyond backup at times. dd can be used on an
MBR or individual partition boot record, and then placed as a file on
somewhere like an NTFS partition; this then could be pointed at by an NT
boot loader as an alternate, and it won't know the difference between
the dd file and the actual partition record. Next time I do something
similar, I think I'll do a dd of my relevant sectors just because of
this post.

If tcsh was your login shell, this would be different than if it is
called from say bash. A shell usually inherits some information from its
parent. If tcsh was directly reading /etc/profile, then there is a bug.

If he runs X and X was started from a bash shell, it is still possible
for his setup to inherit some attributes of the starting/parent shell
(possibly gnome-terminal if he uses gnome). To know for certain, he'd
have to login at console only (avoid the complications of X), do a ps
fxa (or similar), and see if his tcsh shell has a parent that is another
shell (the "f" of ps fxa tells it to show processes as a tree, based on
parent). From within a tcsh that has no other shell for a parent, he
could then
echo $PERL5LIB
To see what it is set at for purely tcsh. Or even gzip /etc/profile to
temporarily disable it, then open another tcsh shell, and see if it has
a different environment from one opened with /etc/profile uncompressed.

You could make a shell script that would do it.
#!/bin/sh
if [ "$1" = "-f" ];then
shift
du -abc $*
else
du $*
fi
Put that script into /usr/local/bin, or ~/bin with the name "du"
and set your PATH variable to have the directory it is in come
before /bin and /usr/bin.
An alias won't quite do what you ask. You can make a totally
different command though, say "alias duf='du -abc'" but that
won't satisfy your desire to make things identical... unless
you make an alias on both systems and then get used to your new
alias rather than sticking with the old command that you are
used to. (I'd probably opt for doing it this way rather than
the script above.)

You may have to change the settings for your SCSI controller to allow booting
from CD-ROM. My RH 6.2 machine has a Buslogic BT 958 SCSI controller and a
SCSI CD-ROM. During bootup, I had to enter <CTRL-B> to get to the SCSI
configuration program (it might be <CTRL-A> on other machines; see the message
that the SCSI controller prints on the screen during bootup).
Once in the SCSI configuration program, I set the "CD-ROM boot support"
flag from OFF to ON.
I was then able to boot from my SCSI CD-ROM.
Your SCSI controller may or may not have this capability; check the installation
manual for details.
Note: Changing the BIOS to allow booting from CD-ROM had no effect; I think
that works only for IDE CD-ROMs.

I should have used a full pathname for 'du' above, e.g., "/bin/du -abc $*".
Note also that the example of a function which can be put into ~/.bashrc
which Neil Cherry provided can also be done using the above:
function du () {
if [ "$1" = "-f" ];then
shift
/bin/du -abc $*
else
/bin/du $*
fi
}
That eliminates the problem of which directory and the PATH variable.

Those should be in the configs. At least with gdm it seems to run xsri
(if installed) in the X server setup script. Find that or uninstall xsri.

Well, now I have to look..
$ less /etc/X11/xdm/Xsetup_0
<snip>
# only set the background if the xsri program is installed
#if [ -x /usr/bin/xsri ]; then
# /usr/bin/xsri -geometry +5+5 -avoid 300x250 -keep-aspect \

There.

So do I. And afio has an advantage over cpio if you use
compression.
I even use afio from linux to back up my Windows partition. It

Do you have access to the relay? If so, you might want to look what the
MTA there has to say.
Of course a firewall can manage connections in both directions. It would
be quite useless if it didn't. I don't know about your setup, but it
should be simply a matter of not blocking incoming connections.
Look at how not blocking outgoing connections is done for your firewall
to get an idea of how this is done.

A simple solution would be to change your alias 'du -f'='du -abc' to
alias du-f='du -abc' (omitting the blank in your alias) or calling
"du -f" instead of du -f (put it in quotes).
Both of these won't enable you to use your alias like du with an extra
option though. You'd have to type something slightly different as you
see. But that shouldn't be a problem unless you want to use this in
scripts where there is no reason to do so.
